in the discharge or dispensing head of a container in a manner that,when the cartridge is opened, gas is discharged into a liquid in thecontainer. Thereafter a discharge control valve is opened to dispensethe charged or aerated liquid from the container. In such structures,separate operating means are provided for opening the cartridge and foropening the discharge control valve, necessitating separate manualoperation of each of the operating means. 7

Accordingly, an object of the present invention resides in the provisionof a discharge head for a siphon or the like which is readily operatedto prepare and dispense aerated liquids.

Another object of the invention resides in the provision of a dischargehead for a siphon or the like wherein operation of a lever or handleserves the dual function of selectively effecting opening of the gascartridge and opening of the dispensing or discharge valve.

Further objects of the present invention reside in the provision of asiphon which presents a neat appearance, is of sturdy construction, andinexpensive to manufacture.

Further objects, not specifically enumerated above, will be apparent asthe invention is described in greater detail in connection with theaccompanying drawing, wherein:

Figure l is a fragmentary sectional elevational view of a siphonembodying my invention; and

Figure 2 is a top plan view thereof.

Referring to the drawing in detail, the siphon comprises a body orreceptacle l and a discharge or dispensing head, cap or closure I2. Thebody If.) is exteriorly screw threaded at M, and the head or closure 12is interiorly screw threaded at I6, whereby the two may be removablysecured to each other. A gasket I8 is mounted in an annular recess I9 inthe head to assure a hermetic seal between the head and the body.

The head I2 has a recess 26 screw threaded at its open end to receivethe screw threaded end of a siphon tube 22 and has a valve seat 2d atits other end to receive a valve 26, which is adapted for movement in avalve chamber 42. The valve 26 includes a valve disc 3!! of rubber,neoprene or other suitable material provided with a tapered extension 32which enters the recess 28 when the 00., Inc., Bloomfield,

valve is seated. The valve 28 has an annular groove 38 in its outer wallaccommodating a packing 36. A valve stem 38 is screw threaded to thevalve 26 at 40, the valve being moved by the stem in the mannerhereinafter described. The

= end of the valve chamber opposite the valve seat 2 3 is provided witha bushing it screw threaded in the wall of the chamber 42 and throughwhich the valve stem 38 extends. A compression spring :35 is carried bythe valve stem intermediate the valve and the bushing 44 for retainingthe valve normally on its seat.

The cap or closure 12 has another recess 59 which is internally screwthreaded at 52 for removably receiving a cartridge support 56. supportis in the form of a hollow cylinder open at its upper or inner endexteriorly screw threaded at 55 for cooperation with the threads 52 toremovably hold the support in place. The other end of the support isclosed and is provided with a thumbpiece 58 whereby the same may bereadily screwed into and removed from the recess 53.

A gas cartridge fill is carried in the support 5%. The diameter of thecartridge is slightly less than the inner diameter of the supportwhereby to slightly space the cartridge from the side walls of thesupport. The contour of the inside of the bottom of the support conformssubstantially to that of the cartridge so that when the support isscrewed into place the cartridge will be firmly held between the bottomof the support and washer 55 in the recess 55. This cartridge contains apressure medium such as carbon dioxide and is provided in its neckportion 52, with a sealing disc 64 which is secured therein, by peepingover the edge of the neck as shown at 65.

Means for piercing or puncturing the sealing disc 64 is positioned inthe cap E2 in alignment with the sealing disc 54 of the cartridge. Thispuncturing means includes a plunger H1, one end of which projects beyondthe body of the cap and is slidably held in the cap by means of a nut12. This plungerhas an annular recess 14 for receiving a packing it. Theplunger is tapered at its inner end to provide a pointed puncturing orpiercing member is. A compression spring 8! surrounds the puncturingmember intermediate a shoulder 82 formed in the can and a shoulder 34formed on the plunger. This spring serves to maintain the puncturingmember normally out of contact with the sealing disc 64 of the cartridgeto.

A lever St is pivotally mounted at 92 on the cap and comprises a handle94 and an arm 96. The cap has a depression 98 conforming substan- Thistially to the contour and dimensions of the handie 53d whereby toreceive the handle when the same is depressed. The arm 98 of the leveris slotted or forked at 109, which fork spans the valve stem 33 and hasa tapered recess to accom modate a tapered head E02 integral with thevalve stem 38.

As will be seen from the drawing, the handle 94 is longer than the arm95 and has an enlarged portion intermediate its pivotal point and itsfree end, to provide greater weight on the handle side of the pivotwhereby the handle will fall by gravity. It will also be seen that thehandle is retained in spaced relation to the cap by the head m2 of thevalve stem. In this way, the lever is retained in neutral or inoperativeposition and is readily operable.

When it is desired to operate the discharge or dispensing head as hereinillustrated and described, the handle as is first raised to move thesame in a counterclockwise direction about the pivot 92, therebybringing the arm 9" into engagement with the projecting end of theplunger '50 and moving the same inwardly. The inward movement of theplunger 19 will cause the puncturing member is to puncture or pierce thedisc 6% of the gas cartridge whereby to permit the escape of gastherefrom. The escaping gas travels downwardly in the space providedbetween the cartridge and the. wall of the support and passes out of thesupport through openings Hit in the wall thereof into the body of thesiphon whereby to aerate the liquid therein.

After the liquid has been aerated, the siphon is ready to dispense theliquid. This is accomplished by depressing the handle t to move the samein a clockwise direction (as viewed) about the pivot 92, thereby liftingthe valve stem 38 which raises the valve ZG-off its seat and permits theaerated liquid to be dispensed by way of the, siphon tube 22 anddischarge outlet or spout Hi5.

When the desired amount of liquid has been dispensed, the handle isreleased, whereupon the spring dd, which was placed under tension whenthe handle was depressed, will return the valve to its seat and thehandle to its normal position, whereby to close and seal the dischargeoutlet.

After the cartridge has been discharged and the liquid aerated in theaforesaid manner, it is not necessary in further dispensing the liquidto again raise the handle, it merely being neces sary to depress thehandle to unseat the discharge control valve.

When all the liquid has been dispensed, and it is desired to rechargethe siphon, the cap 12 may be unscrewed from the body, the cartridge support unscrewed from the inside of the cap, the used cartridge replacedby a new one, a new supply of liquid placed in the container and the capreplaced on the body, whereupon the siphon is again ready for use.

As will be'seen from the foregoing, the present invention provides asiphon or liquid dispenser which is readily operable to prepare anddispense charged or aerated liquids and which is operated by simplemanipulation of a single lever.

As various changes may be made in the form, construction and arrangementof the parts herein, without departing from the spirit and scope of theinvention and without sacrificing any of its advantages, it is to beunderstood that all matter herein is to be interpreted as illustrativeand not in any limiting sense.

It is also to be understood that the following claims are intended tocover all the generic and specific features of the invention hereindescribed, and all statements of the scope of the invention which, as amatter of language, might be said to fall therebetween.
